Power is generated at 480 volt and utilized at 120V. The generator is idealbut the load is at some distance from the generator and hence line losses are appreciable, 1.2 ohms for bothwires. The equivlent load resistance would draw 15kW at unity PF if 120V were provided. Calculate the load voltage, the load power, and the efficiency of the transmission system under the following schemes. a. 4:1 transformer at generator b. 4:1 transformer to load c. 1:4 transformer at the generator and a 16:1 transformer at the load
